get all the library inti's and functions to behave
multiple init calls should not cause undefined behavior
#5 Updated by David Schultz about 10 years ago
Multiple xbee init works if you call terminate at end of use before initing again. Otherwise it will get stuck in an infinite loop waiting for a response that won't come. We should probably make the call return an error if it waits for over a second with no response.
